Light meson masses and non-perturbative renormalisation in 2+1 flavour domain wall QCD
C. Allton, D. J. Antonio, P. A. Boyle +13
We present results for the light meson masses, the bare strange quark mass and preliminary non-perturbative renormalisation of B_K in 2+1 flavour domain wall QCD. The ensembles use…
Light meson masses and decay constants in 2+1 flavour domain wall QCD
D. J. Antonio, K. C. Bowler, P. A. Boyle +9
We present results for light meson masses and psedoscalar meson decay constants in 2+1 flavour domain wall QCD with the DBW2 and Iwasaki gauge actions, using lattices with linear s…
The effect of sea quarks on the mass of the charm quark from Lattice QCD
A. Dougall, C. M. Maynard, C. McNeile
We compute the mass of the charm quark using both quenched and dynamical lattice QCD calculations. We examine the effects of mass dependent lattice artifacts by comparing two diffe…
P-wave Radial distributions of a Heavy-light meson on a lattice
UKQCD Collaboration, A. M. Green, J. Koponen +1
This is a follow-up to our earlier work for the charge (vector) and matter (scalar) distributions for S-wave states in a heavy-light meson, where the heavy quark is static and the…
Lattice QCD with mixed actions
UKQCD Collaboration, K. C. Bowler, B. Joó +3
We discuss some of the implications of simulating QCD when the action used for the sea quarks is different from that used for the valence quarks. We present exploratory results for…
The charm quark mass with dynamical fermions
UKQCD Collaboration, A. Dougall, C. M. Maynard +1
We compute the charm quark mass in lattice QCD and compare different formulations of the heavy quark, and quenched data to that with dynamical sea quarks. We take the continuum lim…
